Rods. Rod mills are similar to bar mills at the front end, but the finishing end is different. Rods have a smaller section (5.5 to 15 millimetres in diameter) and are always coiled, while bars are normally shipped in cut length. The final rolling in rod mills often takes place in a close-coupled set of 10 pairs of small rolls (200 and 150 ...

Mills: What are they? How are Mills used? Advantages
Rod Mills. In contrast to ball mills, rod mills employ long rods as the grinding medium. Similar to grinding balls in a ball mill, the rods tumble inside the mill to grind materials like limestone or various ores. The length-to-diameter ratio is kept between 1.4 and 1.6 to avoid circumstances that might result in rod charge tangling.
